Is it possible using nginx to essentially look at the http referer header,
and if its set to a specific value, and the page is index.html or /,
redirect to a custom landing page.
For example:
# Psuedo code
if($page = "index.html" and $http_referer ~* (www\.)?amazon.com.*) {
rewrite ^ "our-amazon-landing-page.html" permanent;
}
